Tim and Charlie started jogging from the same point. Charlie started jogging 10 minutes earlier than Tim. Tim's jogging speed was 400 m/min and Charlie's jogging speed was 150 m/min. They went in the same direction and did not change their speeds throughout.

1. How long did it take for Tim to catch up with Charlie? 
2. What distance would Charlie have jogged when Tim caught up with him?  Express your answer in meters.

	Tim	Charlie
Speed	400 m/min	150 m/min
Start time		10 min earlier
Extra distance covered at first		1500 m

(a)
Distance that Charlie covered when he jogged 10 minutes earlier
= 10 x 150
= 1500 m

Distance that Tim covered more than Charlie per min
= 400 - 150
= 250 m

Time that Tim needed to take to cover the additional 1500 m
= 1500 ÷ 250
= 6 min

(b)
Time that Charlie would had jogged when Tim caught up with him
= 6 + 10
= 16 min

Distance that Charlie would have jogged when Tim caught up with him
= 16 x 150
= 2400 m

Answer(s): (a) 6 min; (b) 2400 m
